  However, in the thing of the said patent document 1, since a moving sheet | seat must support a user's body weight only with one slide guide means provided in the seat surface part of the fixed sheet | seat, an extension leg part is provided and a body weight is provided. Although it is supported, the moving sheet is only supported in a cantilevered manner by the slide guide means until the moving sheet is installed on the road surface by the extensible foot, so that the vehicle is weak in strength. Sliding in the width direction is difficult to perform smoothly. Further, in the above configuration, since the support of the moving sheet with respect to the fixed sheet becomes unstable, there is a problem that it is difficult to ensure the holding performance of the moving sheet against the impact force applied to the vehicle. On the other hand, since the child seat described in Patent Document 2 is merely installed in an existing seat device, when the infant is put on or taken down from the child seat, the guardian places the upper body in the passenger compartment. There is a problem that the vehicle must be ridden in a cramped posture with a posture to thrust into the vehicle, increasing the physical burden on the arms and waist, and hitting the infant's head against the door opening.
